Application led September 13, 1913. Serial No. 79U,491.

and having also an inserted non-removable plug securing the stopper in position.

The inventionalso comprises a provision to prevent the bottle being `illed by inverting it in a vessel of the liquid which it is required to hold.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 being a vertical section of the bottle neck having the non-refillable closure complete, and Fig. 2 is a cross section of the bottle neck and stopper through the pouring aperture. Fig. 3 is a detailed cross section on the line 3 3 of Fig. 1.

In these drawings 2 represents the neck of the bottle, the bore of which is accurately moldedor is ground with a slight taper as far as is necessary to form a seat for the stopper and in the upper part of' the neck is a lateral pouring aperture 3.

Seated within the lower part of the bottle neck and extending a short distance above the lateral pouring aperture 3 is a hollow stopper 5 which has a sealing ring 10 of cork or other suitable material fitting a shouldered recess provided for it in the lower end. The full diameter of the bore of this stopper 5 is open to the upper end, and at the lower end there is an aperture 7 which is axial with the bore and of smaller diameter.

A buoyant hollow valve 3 loosely fits the bore of this stopper, which valve has a hemispherical lower end' which seats over the aperture 7. To the lower end of this valve 8 a weight 13 is suspended by a fine wire or filament 6, which weight is also connected by a similar' filament to a spur 13 projecting downward from the underside of the stopper l5 and bent into axial alinement with the valve S. This filament connection between the weight 13 and spur 13 is of such length as will allow thc valve to move off its seat a suiiicient amountonly to provide passage through the aperture 7.

In the side of the bore 19 of the stopper which is toward the pouring aperture 3 of the bottle, two vertical flutes or grooves 15 are formed in the bore and extend from the upper edge as far as the seat of the valve. To enable these flutes to be formed in the thickness of the wall of' the stopper' the axis of the bore of it is eccentric with the outside of the stopper.` Toward the upper end of the stopper, each flute 15 connects with a passage 1G on each side delivering to the outside of the stopper, which passages connect there with a passage 17 which is carried around the outside of the stopper and connects the inner bore of' it with the pourino` aperture 3 of the bottle neck. This stopper 5 with its valve 3 is inserted in the neck of the bottle and seats therein with the upper edge of it iust above the lateral pour ing aperture 3 and over it in the neck of the bottle is inserted a locking plug 2O which is provided with a sealing ring 21 of cork or similar material around its lower end and with a circumferential groove 23 which registers with a similar circumferential groove in the neck of the bottle and into these grooves small balls 2li are passed from magazine ducts within the stopper. This locking stopper being the subject of a separate application need not be further enlarged upon. It is designed to be non-removable after it has once been inserted.

In use, the bottle being filled in the usual manner, its stopper 5 and locking plug 2O are inserted and the pouring aperture 3 is closed with a small cork and may be sealed. When this cork is removed `from 3 and the bottle is tilted, as in the act of pouring, the liquid acting on the underside of the valve 8 will lift that valve and will flow through the aperture 7 and along the grooves 15, and through the opposed ducts 16 and passage 17 to the pouring aperture 3. Un turning the bottle to its vertical position the valve v3 will close the aperture 7 by its own weight and that of the weight 13 connected to it. The bottle cannot be aperture 3 can not pass the valve 8. It the bottle is inverted and immersed in a liquid the buoyancy of the hollow valve 8 will hold it against its seat and prevent ingress and if it is laid on its side the weight 13 will hang on its filaments, as indicated by theV dot and dash lilies in Fig. l, and hold the valve 8 to its seat unless, as 1n pouring,`

there is a fluid pressure within the bottle.

The bottle stopper and its several correU; `lated parts may be made of any suitable' material that will be non-corrosive under the action of the liquid the bottle is designed to hold'.

Having now particularly described invention, I hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:

Vl. In a non-refillable bottle, a bottle neck having a lateral pouring aperture, a hollow stopper secured within the neck of the bottle the upper edge of the` stopper extending' above the bottom of the lateral pouring aperture said stopper having an aperture in the `bottom end and a passage in the upper part connecting the cavity of the stopper indirectly with thepouring aperture of the bottle, and a buoyant valve seated within the stopper over the bottom aperture. v

2. In a non-reiillable bottle, a bottle neck having a lateral pouring aperture, a hollow stopper secured within the neck of the bottle the upper edge` of the stopper extending above the bottom of the lateral pouring aperture said stopper having an aperturein the bottom end and a passage in the upper part connecting the cavity of the stopper indirectly with the pouring aperture of the bottle, a buoyant valve seated within the stopper over the bottom aperture means for limiting the upward movement of this valve,

and means for holding the valve on its seat when the bottleis inclined from the vertical bottle, a buoyant Valve seated within the stopper over the bottom aperture, a flexible connection fromthe underside of the valve to an attachment projecting downward from` the underside of the 4stopper and a weight about the mdlength ofsaid connecv tion.

S. In a. non-rellable bottle, a bottle neck having a mouth and a lateral pouring aperture, a yhollow stopper litted into said neck below the lateral pouring aperture, and including a portion extending above the bottom of the lateral pouring aperture, said hollow stopper having a chamber extending from its upper end toward its lower end and restricted at its lower end to form a valve seat, said stopper having a peripheral groove Vregistering with said lateral pouring` aperture and having an aperture to form communication between said groove and the interior of the stopper chamber, a valve mounted in said stopper chamber to engage said seat, means continuously tending to hold said valve on its seat and a locking plug inserted in the bottle neck above said stopper to close the upper end of the stopper chamber and close the bottle neck mouth substantially as shown and described.

9. As a bottle closure for bottles having a mouth and a lateral pouring aperture, a stopper adapted to be inserted in the bottle neck and extend below the lateral pouring aperture, said stopper having a chamber extending trom its upper end toward its lower end and terminating at its lower end in a restricted valve seat portion, a buoyant valve mounted in said stopper chamber, and conforming closely to the same, said stopper having longitudinal flutes for conducting the liquid by said valve when said valve is unseated, a plug for closing the bottle neck mouth and also closing the stopper chamber at its upper end, said stopper having a lateral opening to deliver through the lateral pouring aperture of the bottle neck.
